Thanks a lot!

Hi! Thanks. It makes things simple.

> We'll also merge https://github.com/radis/radis/pull/495 , which implements in Radis (and therefore in the API) the non-air broadening parameters Cool! Thanks a lot! @erwanp

OLA implemented in #283 and #284

Ah, I see. We can directly use `_calc_oa_lens()` to determine the optimal size of `block_size` because it does not need to be JITtable. I'll try to use it. Thanks!

You're right. L is much larger than I thought. Assuming the filter length of 50cm-1 @5000cm-1, the optimal block size is ~ 500cm-1. So, for instance, when we would compute...

Because I almost finished the implementation of PreMODIT, I restarted PreSOLAR algorithm, which aims to reduce the computational cost rather than device memory use. Also, it includes the cutoff of...
